Abstract
A backlight module and a display device are provided by the embodiments of the present application. The backlight module includes a light guide plate and a switchable diffusion sheet. The switchable diffusion sheet further includes a first conductive layer and a second conductive layer disposed opposite to each other. A polymer liquid crystal layer is disposed between the first conductive layer and the second conductive layer. In the backlight module of the embodiment of the present application, a thick glass in the prior art is replaced with the first conductive layer and the second conductive layer which are lighter and thinner than the thick glass, which can greatly reduce an overall thickness of the backlight module.
Claims20
A backlight module, comprising:
- a light guide plate;
- a switchable diffusion sheet disposed above the light guide plate, the switchable diffusion sheet comprises a first conductive layer and a second conductive layer arranged oppositely, wherein a polymer liquid crystal layer is disposed between the first conductive layer and the second conductive layer;
- when the switchable diffusion sheet is energized, the polymer liquid crystal layer is in a light-transmitting state, and when the switchable diffusion sheet is non-energized, the polymer liquid crystal layer is in a light-blocking state.
